The Gray streams proposal (and the implementations I've seen) is
silent on READ. Is this because READ is supposed to be implemented on
top of READ-CHAR &al?

This is not just a theoretical question. I'm trying to make ABCL's
support for slime a little more robust, and the interaction of READ
with user defined streams is one of the major stumbling blocks.

Yes.

So it depends on an implementation detail. Strange. 
But thanks, anyway!

Gray Streams are not part of the standard at all, so everything about 
them depends on implementation details.

Just because something is not part of the standard, it doesn't mean it
has to depend on implementation details. And if it does, it's nice if
those details are made explicit. Nevertheless, I shouldn't have called
this 'strange'. After all, the proposal says: "The hard part would be
re-writing existing I/O functionality in terms of methods on these new
generic functions." So true :-(
